摘　　要：主要考察了四氯化碳气相、液相催化加氢反应中载体的选择和活性组分的选择,在液相反应中活性炭是较佳载体,钯是合适的活性组分;而在气相反应中,三氧化二铝是较佳载体,铂是合适的活性组分。同时考察了铜和银的加入构成双金属催化剂在四氯化碳加氢反应中的性能,在液相反应中银的加入提高了氯仿的选择性,而在气相反应中铜的加入提高了四氯乙烯的选择性。Selection of active components and catalyst supporters was investigated in catalytic hydrodechlorination of carbon tetrachloride in liquid-phase and gas-phase.Active carbon was the best supporter and Pd was the suitable component in the liquid phase,while Al2O3 was the best supporter and Pt was the suitable component in the gas phase.Meanwhile,the performance of bimetallic catalyst formed by adding Cu and Ag in catalyic hydrodechlorination of carbon tetrachloride was also studied.h was found that adding Ag to form bimetallic catalyst increased the selectivity of CHCl3 in the liquid reaction and adding Cu increased the selectivity of C2Cl4 in the gas reaction.
